Electronic invoices often arrive via email while you are out of the office. The good news is that you can read an electronic invoice from your phone in seconds, on both Android and iPhone.

Why the phone doesn't open .p7m

The invoice is an XML file inside a signed .p7m envelope. The smartphone does not recognize the format and shows a file that does not open. You need a tool that extracts the invoice from the envelope.

Read the invoice on Android

On Android you have two convenient ways:

  • Free P7M Viewer app: install it from Google Play, then open or share the .p7m file to the app from email, WhatsApp or File. The invoice appears immediately.
  • Browser: open the P7M Viewer site, tap Choose file and select the .p7m invoice.

Read the invoice on iPhone

On iPhone and iPad:

1. Save the .p7m attachment from the email to the Files app.

2. Open the P7M Viewer site with Safari.

3. Tap Choose file, select the invoice and view it.

Save or send the invoice

After opening it you can download the XML or save it as a PDF from the Share menu on your phone, to forward it to your accountant or archive it.

Advice

If you receive invoices frequently, the free P7M Viewer app for Android is the quickest solution: open and share your invoice with one tap.
